Ecchymoses are purple flat patches on the skin that are commonly known as bruises.
What is the Pathology of Ecchymoses?
The pathology of ecchymoses is:
-Etiology: The cause of ecchymoses is typically trauma.
-Pathogenesis: The sequence of events that lead to ecchymoses is a bursting of small blood vessels that allow blood to leak under the skin.
-Morphology: The morphology associated with ecchymoses shows non-blanching, purpuric flat lesions.
How do Ecchymoses Present?
Patients with ecchymoses typically are females present in the age range of older years. The symptoms, features, and clinical findings associated with ecchymoses include an area of skin discoloration larger than 1 centimeter.
How are Ecchymoses Diagnosed?
Ecchymoses are diagnosed with a physical exam.
How are Ecchymoses Treated?
Ecchymoses are treated with symptomatic management.
What is the Prognosis of Ecchymoses?
The prognosis of ecchymoses is good.
